Detailed Description

Stackage LTS 11 was released in March, it unlocks newer versions of a number of import Haskell libraries and other packages.
GHC and its core libraries remain unchanged compared to LTS 10, so only about half the packages will need to be rebuild (about 200 version bumps and their reverse dependencies).

(The just released Stackage LTS 12 which has a major ghc version bump to 8.4.3 will wait for Fedora 30.)

Benefit to Fedora

Fedora users will have a newer version of Haskell Stackage LTS packages to use and develop on.

Scope

Proposal owners:

Bump the affected Haskell packages from LTS 10 to LTS 11 using cabal-rpm, rpmbuild-order and fedora-haskell-tools

Build them and their reverse dependencies for Rawhide (using f29-ghc sidetag to avoid disruption)
